P0720 on Skoda: Causes, Symptoms and Fix Cost
Quick Answer
High SeverityNot safe to driveSkoda
P0720 on a Skoda means the transmission control module is not receiving a proper signal from the output speed sensor. This sensor measures how fast the transmission output shaft rotates, which determines vehicle speed and helps the TCM calculate gear ratios and shift points.

Skoda Octavia
2004-2024Octavia models with the DQ200 and DQ250 DSG transmissions share the same output speed sensor design as the VW Golf. On DSG models, the sensor is part of the mechatronic unit, making individual replacement more complex. The conventional 6-speed Aisin automatic used in some Octavias has an externally mounted sensor that is simpler to replace.

How to diagnose P0720 on a Skoda with OBD2
Follow these steps to pinpoint the root cause of P0720:
- Check if the speedometer is working. A dead speedometer alongside P0720 strongly points to the output speed sensor, since both the transmission and instrument cluster rely on this signal.
- Locate the output speed sensor on the transmission housing (typically near the tail shaft or differential housing). Inspect the connector for corrosion, loose pins, or damage.
- Measure sensor resistance with a multimeter and compare to manufacturer specifications (typically 300-1200 ohms). Also check for signal voltage while spinning the sensor manually if accessible.
- Use a scanner to monitor live data and compare input speed versus output speed readings. The output speed should correlate with vehicle speed and the current gear ratio.
- If the sensor and wiring test normal, inspect the transmission fluid for metal contamination. Debris on the magnetic sensor tip can cause signal distortion.
